IMPROVEMENT IN CUTTING APPARATUS FOR HARVESTERS.

Spccificationforming part of Letters Patent No. 33,966, dated December17, 1861.

To all whom, it may concern:

Be it known that we, ABRAHAM SToLER and SAMUEL A. SrssoN, both of thetown of Bris tol, in the county of Bucks and the State ofI Pennsylvania,have invented a new and useiul Improvement in the Cutting Apparatus ofHarvesting-Machines; and we do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings and the letters of reference marked thereon, ofwhich- Figure l is a horizontal or top view. Fig. 2 is a posteriorvertical view of a section of the beam and other parts of the apparatus.Fig. 3 is a side view of the guard C. Fig. 4 is a side view of theconical-headed 'bolt D used in retaining the cutter to its proper place.Fig. 5 is a posterior vertical view of a section ofthe connecting andreciprocating rod E and the rear end of the cutter and its pin. Fig. 6is a top view of the cutter F.

The letters of reference marked thereon are the same in all the figures.

The beam is composed of two plates, A and B. The upper plate, A, iscountersunk from the under side to receive the conical head of the boltD. The lower plate, B, is much narrower, and is drilled from top side toreceive the steadying-pin oi' the conical bolt D. `By this arrangementmuch weight of material is dispensed with and a sufficient strength ofbeam obtained.

The guards C are placed underneath the two plates A and B of the beam,the whole being secured and kept to their places by means of thescrew-bolts G.' The guard C, Fig. 3, isA :formed with an uprightprojection at the rear end, which is equal in height to the thickness ofthe plate B, whereby a bearing against the plate A is obtained, and thebolt G is much relieved and the firmness of the guard much improved.

The cutter F, Fig. 6, is formed with a square aperture near its center,which takes the square shank of the retaining-bolt D. Near its rear Theretaining-bolt D, Fig. 4, is formed with an ordinary screw-nut, s, asquare shank, t, a conical head, a, and a round steadying-pin, o, orprojection to said head, the whole forming a cheap, effectual, "anddurable apparatus.

We are aware that the principle of cutting grass and grain by means of ashear cut is not new.

We are also aware that great difficulty has been experienced in sosecuring the cutters as to avoid their soon becoming loose and slippingover the tougher portions of the grass. The arrangement described issuch that the cutters are kept uniformly to their place in a simple andeffectual manner, requiring no'special knowledge on the part of thefarmer to keep in order, hence the machine can always be relied on forperforming its work.

Vhat we claim as our invention, and wish to secure by Letters Patent, is

The bolt D, when formed with a square shank and conical head, whetherwith or without the steadying-pin at its base, as shown by us in theabove, when used in combination with the ringer-bar and cutter, in themanner and for the purpose specified.
